I know I'm human. And if you were all these things, then you'd just attack me right now, so some of you are still human. This thing doesn't want to show itself, it wants to hide inside an imitation. It'll fight if it has to, but it's vulnerable out in the open. If it takes us over, then it has no more enemies, nobody left to kill it. And then it's won.

MacReady: I dunno, it's like this: thousands of years ago this spaceship crashes, and this thing, whatever it is... gets thrown out or crawls out and it ends up freezing in the ice.Garry: So, the Norwegians find it, and they dig it out of the ice... MacReady: That's right, Garry. They dig it up. They cart it back to their base. It gets thawed out, it wakes up, probaly not the best of moods, and... I don't know, I wasn't there!Childs: How could this motherfucker wake up after thousands of years frozen in the ice?George Bennings: And how can it make itself look like a dog? MacReady: I don't know. Because it's different then us. Because it's from outer space. What more do you want from me? Ask Blair!
